Hello!
On 1.18.1, I heard a constant forest sound underground, which is not supposed to happen.

If these bird sounds come from the fact that I'm in a lush cave, it's weird too, lush caves aren't supposed to have birds.

There are no birds playing. At least not from AmbientSounds. Only some crickets and a frog from time to time. I'm still not sure what the lush cave should sound like, but that's my current attempt. If you have better ideas let me know.
